The condensation product from a tertiary base and an alpha-halogenmethylether' and the mixed polymerization product may also be, applied in separate baths, each by itself, in either order of succession. The method used is the same as above.

As alpha-halogenmethylethers ofthe abovenamed general formula there may be mentioned for instance: alpha-halogenmethylethers of alcohols containing at least 12 carbon-atoms, such as for instance dodecylalcohol, tetradecyialcohol, cetylalcohol, octadecylalcohol, oleylalcohol, montan wax alcohol, furthermore the alcohols obtainable by catalytic reduction of resinic acids, moreover alcohols having the constitution of alkyl phenoxyethylalcohol, alkylphenylalkylalcohol, alkylbenzylalcohol, the alkylcyclohexanoles, the carboxylic acid ethanol amides and so on.

The condensation products of the alpha-halogenalkylethers of said alcohols are obtained by means of aliphatic tertiary amines or aromatic tertiary amines or heterocyclic bases containing tertiary nitrogen. The said tertiary bases may contain the tertiarily bound nitrogen once or sev- In the latter case the alpha-halogenmethylethers may have entered the molecule of the tertiary base several times. There may be formed, for instance, the reaction products of dodecylchloromethylether with tetramethylmethylenediamine, tetramethylethylenediamine and so on.

By the combination described in the present application a number of considerable improvements is attained in comparison with the methods hitherto known for imparting water-repellency to textile materials. Thus, the hydrophobic properties of the treated fabrics are greatly enhanced, This increase is more than the additive effect of the individual agents used and results especially in the fastness to washing of the effect attained. Besides, the fiber materials which have been treated with the condensation products from tertiary bases and the above-named halogenmethylethers show the drawback of disadvantageously influencing the shades of many substantive dyes and, above all, of damaging their fastness to light even considerably under certain circumstances. By the use of the condensation products from a tertiary base and alpha-halogenmethylether in combination with, for instance, a mixed polymerizate from maleic anhydride and a vinyl compound of high molecular weight it is possible to prevent to a high degree the said damage and deleterious affect of the fastness to light of substantive dyestuffs.

The following examples serve to illustrate the invention, but they 'are not intended to limit it thereto:

1. Artificial silk fabric is treated with a hot carbon tetrachloride solution containing per liter grams of a mixed polymerizate from maleic-anhydride and octadecyivinyl ether and 10 grams of stearoxymethylpyridinium chloride. The

amazes material is then freed, by centrifuging, from the excess of solution and finally heated to 120 C. for half an hour. The material has thus become very hydrophobic.

Viscose artificial silk is treated with an aqueous emulsion, heated to 50 C., which contains per liter grams of stearoxymethylpyridinium chloride, 2.3 grams of the mixed polymerizate from maleic anhydride and octadecylvinylether, 7 grams of paraflin and 1.2 grams of polyvinylalcohol. The fabric is then squeezed and heated to 120 C. to 130 C. for 20 minutes.

6. Cotton calico is treated for half an hour with an aqueous solution of 1 per cent. strength of the quaternary ammonium salt obtained from octadecyl-chloro-methyl ether and dimethyl-aminoethylmethyl ether:

The material is centrifuged and dried at 80 C. The fabric thus obtained is to a great extent impermeable to water- 7 Woolen, silk or artificial silk clothing material is treated for 5 minutes in a solution c0ntaining per liter of carbon tetrachloride 5 grams of the mixed polymerizate from maleic acid monododecylester and vinyldodecylether and dried in the air. After evaporation of the solvent. the material is introduced into a second bath containing per liter of water 10 grams of stearylhydroxymethyl-pyridinium chloride, The material is subsequently squeezed and dried for about 1 hour at 80- C, to 100 C.; it is then washed in another aqueous solution containing per liter 5 grams of sloziip and 2 grams of sodium carbonate, rinsed and r ed.
